The wavelength of the photon emitted when an electron jumps from n = 5 to n = 2 is
Q1. The wavelength of the photon emitted when an electron jumps from n = 5 to n = 2 is
Answer: 434.1 nm
Explanation: Using Rydberg formula for n = 5 to n = 2 transition, 1 / λ = R * (1 / 2² - 1 / 5²), giving λ = 434.1 nm.
